【摘要】：崖城13-1气田是我国首个海上气田,也是南海西部海域第一个发现和对外合作开发的高产大气田。通过对该气田20年开发过程中挑战对策及开发经验进行系统的思考回顾,总结探索出了指导崖城13-1气田高效开发的技术策略:1整体部署、分步实施的开发策略贯穿全程,少井高产的开发理念以及各开发阶段因时而异的开发技术政策引领高效开发;2开发阶段滚动调整、均衡开采,以准确认识气田为前提,合理挖潜气田,确保稳定供气;3多专业结合,研究技术配套,开展储层精细描述技术和见水综合评价,并实施降压生产技术,以减缓气田产量递减、提高气田采收率。高效开发策略与技术的成功实践使崖城13-1气田保持了16年的稳定生产,高峰年产气量达到35.5亿m3,为南海西部地区万亿m3大气区的建设奠定了基础,对后续其他海上气田的开发有重要的指导和借鉴作用。
[Abstract]:Yacheng 13x1 gas field is the first offshore gas field in China, and it is also the first high-yield gas field discovered and co-developed in the western waters of the South China Sea. Through a systematic review of the challenge countermeasures and development experiences in the 20-year development process of the gas field, the technical strategies guiding the high-efficiency development of Yacheng 13-1 gas field are summarized and explored: 1) the overall deployment, step-by-step implementation of the development strategy runs through the whole process. The development idea of low-well high-yield and the development technology policy of different development stages lead to high-efficiency development; (2) the rolling adjustment and balanced production in the development stage, taking the accurate understanding of the gas field as the premise, tapping the potential gas field reasonably and ensuring the stable gas supply; (3) combination of multi-specialty, research technology, development of reservoir fine description technology and comprehensive evaluation of water, and implementation of pressure reduction production technology, in order to slow down gas field production decline and improve gas field recovery. The successful practice of high efficiency development strategy and technology made Yacheng 13m 1 gas field keep stable production for 16 years, and the peak annual gas production reached 3.55 billion m3, which laid a foundation for the construction of billionm3 atmospheric area in the western part of the South China Sea. It has important guidance and reference for the development of other offshore gas fields.
